An implantable loop recorder is a small device used to detect and record abnormal heart rhythms that occur infrequently. It is especially useful for diagnosing the cause of unexplained fainting spells, or for excluding a rhythm disorder that happens very infrequently.
Implantable loop recorder
01Why It’s Done
Dr Lee may recommend this for patients with:
Investigating infrequent palpitations
Diagnosing the cause of unexplained blackouts or fainting
Long-term monitoring for atrial fibrillation, a cause of cryptogenic stroke
02How It Works
A device smaller than a USB drive is inserted just beneath the skin of the chest under local anaesthetic and light sedation
It automatically records abnormal heart rhythms.
You or a caregiver can also activate it when symptoms occur.
Data is downloaded in clinic or sent via a remote monitor; the battery lasts over 24 months.
03Duration, Recovery & What To Expect
Insertion is a brief procedure (around 5 minutes) under local anaesthetic and light sedation with minimal downtime. It is done as a day case in hospital or day surgery centre. The device monitors quietly in the background of daily life.
